I've just picked up a Sip Spotomatic spot welder, which although it appears to be in good condition, doesn't want to play ball. It's marked as 2019.
When operating it either does nothing, blows the fuse, or trips the mains. On very rare occasions it produces a weld.
Not sure what the problem...
More shakey than unsteady :)
It is a tricky process, made worse by the weld pool not being molten as such so you I was trying various ways to move the weld pool along. I'll be re-visiting this process as I can see a lot of uses for it for non structural car bodywork. I also have a fuel tank to...
In a word, fantastic, been putting together the chassis for my Beach Buggy over the past few weeks. Mostly 3-5mm box and plate and it has performed far better than my talents show
yes, it is. I need to play with it a bit more to get tidier joins but I've got another project in mind for that. I was impressed with it though and the machine makes life so much easier
the second repair was made to the area where the steering column paases through the tank (tractor!)
my technique improved by the last bit and I think I hadn't cleaned the top enough
very happy with the results and this was a good choice od process for this repair. There is still a slight...
finally got a chance to try it out today, first mistake was I hadn't ordered a 1.0mm tip but I got by with the very worn tip off my old welder :( I set the machine to Cusi (gas is set to argon automaticaly) and set the metal thickness
first pass was ok, but a little messy, so I turned the...
I recently replaced my ancient 150 amp Sealey transformer machine with a Kemppi 200 Minarcmig inverter machine. Light years ahead, fantastic machine that makes welding a breeze and a pleasure. Consistent, quality welding, fantastic penetration, I should have done it years ago.
It'll either be 1 or 1.2 mm mild steel. Haven't checked yet, but I want to experiment with the technique as I can see it being usefull for letting in non structural panels on the classic cars I normaly work on.
so there are more benefits to using it in this instance than I first thought, thanks for the info
I've got a cylinder of Argon, hadn't realised how expensive the wire was though!
The tank's already been cleaned plus I'll probably be replacing the entire bottom with fresh steel. I was thinking the braze would flow and seal better with less chance of leaks than MMA?
Is Cusi3 suitable for replacing the bottom of a tractor diesel tank? I havent welded with it before so this is a learning curve, also I'll be using my new Kemppi Minarcmig 200
thanks
